摘要: 地下水封石洞油库是最好的储油形式,建设需求迫切。受限于国外技术封锁,国内多个大型洞库都是在缺乏必要的技术标准和建设标准的情况下直接进入工程实践,因此也带来了诸多挑战。通过对水封石洞油库相关文献的梳理,深化了对我国水封洞库选址、围岩稳定、围岩渗透性、水幕系统设计及应用、渗控等关键技术的理论和实践认识。当前洞库勘探、设计、施工仍主要基于连续介质理论和方法,对岩体中裂隙控制作用的认识和研究还不够充分,是导致目前洞库工程实施困难的首要原因。结合当前工程实践中面临的问题,提出水封洞库后续工作中应继续加强基础研究工作力度、加强总结和规范编制工作力度、进一步放开行业准入资格等建议。

Abstract: Considered as the best way to store oil, underground oil storage in rock caverns is in urgent need for the national petroleum reserve. Subject to the technical blockade of foreign countries, many large caverns in China are directly undergoing engineering practice with no technical standards or construction standards, posing a great deal of challenges. By sorting out literatures on water-sealed oil storage caverns, we discuss in this paper our theoretical and practical understandings of such key technologies as site selection of water-sealed oil storage caverns, stability of surrounding rock, permeability of surrounding rock, design and application of water curtain system, and seepage control. Current survey, design, and construction are mainly based on the continuum theory and methods, and understanding on rock fissure control is insufficient, resulting in the difficulties of constructing water-sealed caverns. In light of problems in current engineering practice, we suggest that fundamental research should be intensified, summaries and standard compiling should be strengthened, and admittance qualification of the industry should be furthered opened.

Key words: underground oil storage in rock caverns, site selection, surrounding rock stability, seepage properties, water curtain system, seepage control
